@heinrich5991 you have to ask fokkonaut, I don't know if the server is public or not

its private

06:44

Heinrich I already wrote you a private msg on discord

Guys

08:20

Hey. I have a question. Is it possible to cut antiping from ddnet and insert it into another client?

well its open source so idk why not

08:22

would be a bit of work tho

I used to know how to do it, but now I just forgot

[ddnet/ddnet] Pull request opened: #1071 Ignore `Makefile`s generated by the CMake Make target

$ gcc --version
gcc (GCC) 7.3.0
[...]

10:50

anyone else have this so we could check how reproducable ddnet is?

10:50

building twice on the same machine with the same build system (ninja/make) seems to produce the same results

10:50

only in release mode

i only have 4.9.2 doesnt apt-get update update this automatically?

yeah, but distributions ship different versions

(i.e. it's normal that different distributions have different versions)

7.3.0 is ridiculously new

i have no higher version than 4.x on any of my machines .-.

11:55

[quakenet] <Learath2> is what I get as the md5sum on my machine

11:55

[quakenet] <heinrich5991> md5sum. really :D

11:55

[quakenet] <heinrich5991> ninja/make?

11:55

[quakenet] <Learath2> I couldn't think of anything else :P

11:55

[quakenet] <Learath2> make

11:55

[quakenet] <heinrich5991> sha256sum is the one btw

11:55

[quakenet] <Learath2> gcc (Gentoo 7.3.0 p1.0) 7.3.0

11:55

[quakenet] <Learath2> not sure if gentoo injects a couple patches tho

[quakenet] <Learath2> 0c14e3c212d65d8f42b800092d615d9337d7d062e88cfc573b6eaba0afac8736 DDNet is the sha256sum btw

12:07

[quakenet] <heinrich5991> yea, different hashs for me

12:07

[quakenet] <heinrich5991> I guess that was a wild idea anyway

12:07

[quakenet] <heinrich5991> we haven't even compared the libs etc. we're linking

12:09

[quakenet] <Learath2> well I most definitely should get a different one

12:10

[quakenet] <Learath2> I compiled everything on this system from scratch, every single one of those would have to be completely reproducible aswell for us to get exact same builds

12:10

[quakenet] <Learath2> actually no, forgot about dynamic linking, stupid

Whenever DDNet client crashes in fullscreen mode I cant do nothing while it running (in my case I cant start debugging it) because game is topmost and hides everything behind of it. Anyone know the way of hiding such windows without closing? (btw closing is not easy also). Win 10 (edited)

i know the way

12:39

12:39

i too have this problem.

can you share your solution please?

1280x1024. as i know, you russian. it's so or i stupid?

lma

12:49

o

how do you debug fullscreen DDNet when you can't see your debugger because DDNet stays on top?

ahaah

12:49

paradox

you guys must be kidding me. Thats what I talking about. I need to hideout the window (edited)

12:50

or any other solution

a troll would answer: I have 1920x1080 (sorry, couldn't resist)

He already did this answer

DDNet crashes rarely, so I dont want change my graphics settings, thats why I`m looking for another solution

12:55

yes, heinrich, I cant see nothing instead of DDNet

12:57

today I had crash on loading stage, what never ever occurs before (few years of using DDNet)

@BannZay have you tried borderless window?

haha

12:59

got another crash, but its not topmost anymore

12:59

well, I`ll take this solution. Thx heinrich

Got the same problem

CTRL+ALT+DEL -> Taskmanager -> then you can create a new virtual dekstop -> move debugger into the new virtual desktop -> debug

14:11

Image attachment

14:11

this symbol

14:11

you can only press windows key on your keyboard after opening the CTRL+ALT+DEL view for some reason

14:13

ALT/WINDOWS+TAB might work too (edited)

[ddnet/ddnet] Pull request opened: #1072 Add broadcast importance (fixes #669)

The broadcast timer is marked as unimportant and it won't overwrite if there was another broadcast sent less than 6 seconds ago. So vanilla clients won't miss any important news c:

@ChillerDragon maybe add the 6 seconds as an option

16:53

that can be modified?

though about it

16:54

i like config vars c:

imo its always good

but thought ddnet dislikes it

no

16:55

i think its the other way around

great

16:56

ill add one

17:03

uhm

17:03

@Ryozuki halp i need a commit name

17:04

im trying to improve my commit messages but all i can imagine sound ugly

17:06

well i add a random name then

@deen got a solution for the crashes?

@fokkonaut I was at work all day

okay

BTW: i tested with vanilla and it never crashes

17:59

its just ddnet and ofc on ddnet based

18:00

o.o

18:00

its vanilla too

18:01

but: just when you really spam the keys i mentioned before. on ddnet 11.0.3 you messed something completely up and its crashing almost always without even doing something

we need to get 11.0.3 back to 10.8.6

[ddnet/ddnet] Pull request closed: #1071 Ignore `Makefile`s generated by the CMake Make target

[ddnet:master] 1 new commit

710d061 Ignore Makefiles generated by the CMake Make ... - heinrich5991

github should really add ff merging...

rebase merging is alsmost the same

[quakenet] <deen> @fokkonaut I don't understand what that server is doing specifically btw. How is it different from just changing map? Is the source code available somewhere?

the source is not available and the thing is, its not a normal map chanhge, something is just commented out or something like this. He doesnt want to tell anyone, but he made it to be a normal change now, its working slow but its working

how is the behaviour any different then a map change?

probably not waiting for answers?

answers?

not following the protocol, anticipating what the client will send and already sending the answers to that as well

sounds useless tbh...

sounds like reducing RTT

a tile performing a map change sounds useless as a whole aswell

oh wow

19:43

you're so unimaginative

it'll just take everyone to a new map

or the server has support for handling multiple maps

19:44

doubt it, if he hacked that toghether he'd be able to run ddnet in a debugger

19:45

but yeah, with that it could be cool

19:46

@heinrich5991 is ddnet/ mapping turing complete?

(edited)

huh? not in a way that I know

I was wondering could one build a computer using switches, doors, tees and stuff

hmmmmm

lost story 2 crashes last ddnet client when opengl 3.3 enabled

@Deleted User are you jupeyy on github? ^

I think so

@Learath2 its a tile that only sends you to another map. yes the server has multi map.

20:03

you can also Watch in spec over the other map

20:04

and he deleted somehthing in the change to make it Switch faster, and that caused crashes at some point (11.0.3 extremely)

[quakenet] <Learath2> should add that to the list of things i'll build someday just to have it open source

20:06

[quakenet] <deen> @fokkonaut Well, figure out what he deleted, that's the cause...

20:06

[quakenet] <deen> probably some data structure isn't initialized yet

he doesnt want to tell me nor anyone else

[quakenet] <Learath2> then he should grab a debugger and figure it out himself...

@Learath2 why u want to make this opensrc?

20:08

The problem only appears on Windows so he Cant debug it

https://forum.ddnet.tw/viewtopic.php?f=6&t=5915

20:09

isn't that the blocker source

[quakenet] <Learath2> I don't know tbh, I derive some pleasure by open sourcing others work by replicating it, information should be free and all

y why

jao yes its the src

open source is ❤

[quakenet] <Learath2> could one of you grab a copy of it? I can't download from google drive from this computer

20:12

[quakenet] <Learath2> open source is unsustainable unless you are a tech giant like google

@Learath2 the server of him is based on vanilla. damage is off by default. If you shoot with ur gun everythings nice. as soon as you Switch the map and shoot gun again it predicts weird, kind of it thinks that you have jetpack on. Can u fix it?

20:13

ofc vanilla Client doesnt have that preditction

[quakenet] <Learath2> I never touched any of the prediction code, not my thing

20:14

[quakenet] <Learath2> it being vanilla makes sense though, I doubt it'd be easy to do the multi map with the spaghetti that is the ddnet source :P

can someone remap this lost story2

20:24

it uses quad layers that are 27000x4800 big

xD

20:25

i guess thats why it crashes

the limit is 2billion bytes

20:25

which is roughly 9.4kx9.4k

20:26

i doubt somebody needs more tiles ever xd

apparently kintaro does

where

20:26

the map is just bad mapped

20:27

he clipped the layers

20:27

the game layer is only around 5kx1k

20:27

oh not even

20:27

2k x 600

20:27

XD

@Deleted User why did it work before?

wait so why does it crash actually, it's well below the limit

i reduced the ram usage

20:28

and since opengl 32 bit only supports native pointer size

20:28

it would be around 4 billion

why is it 32 bit only

the 32 bit opengl is 32 bit

20:29

because it uses native pointer sizes

20:29

it's just made like that bcs it makes sense somewhere

20:29

well i can double the size again

20:29

but that would add 4 bytes more on system ram

20:30

np for normal 64 bit users

no probnlem i guess?

20:30

:)

learath

20:30

well it's somewhere ram waste

anyways, is it even okay to go around breaking maps?

easiest would be to use #pragma

20:30

but heinrich appearently saw its not standard

@Deleted User you say you reduced ram usage – why did it work before and now it doesn't? because of reduced address bits?

you can pack things without pragma

@heinrich5991 yes

20:31

i use 1 bit of the pointer

@Deleted User pragma doesn't reduce space

so it doesnt add 4 bytes

20:31

well pragma push

20:31

pack(push, 1)

on what struct?

means 1 byte alignment

20:32

on maplayer.h the tile visual info

STileVisual?

mh actually just the tilelayers have to be fixed

that's 4 bytes

yes

20:33

4 bytes = 2 billion bcs 1 byte is used

#pragma(pack) doesn'T change that it uses 4 bytes

with 4 billion would be double the size for the pointer, but 4 bytes more for the boolean at normal alignment

20:34

#pragma pack(push, 1)

yes, that

20:34

it doesn't change the size of that struct

u have to add a boolean

20:35

since i would need 1 byet more

20:35

but at normal alignment that would be 4 bytes

ah

i mean the map probs doesnt load on 32 bit anyway xD

can someone try with 32 bit and the old rendering?

probs only 32 bit users are windows and that limits the ram to 2-3 gb

20:36

well with old renderer maybe

which map was it?

i can test it fast

20:37

lost story 2

@Deleted User maybe one could use the least significant bit of the offset?

am i not doing it?

you're using the most significant one

20:38

resulting in only half the address space being available

mhh yeah

20:38

probably works

20:38

since the number is even

\o/

still these maps are using much ram bcs of bad mapping

20:40

even with the old renderer it takes ages to load

it's not really bad mapping if it achieves something different

I thought it was needlessly big?

maybe an abuse of mapping

20:41

idk how it achieves the effect or if it legitimately needs the huge space but it is quite a different map

but when the game layer is so small

what layer is so bad mapped in lost story 2?

why would there be a tilelayer be so big

20:41

dunno there are so many

give an example

its fact

EXAMPLE

i cant prove it it must be like that xD

what

90% of the layers have zero width xD

literally zero or figuratively zero?

most are mapped good*

20:45

but i cant find the fucking map layer

its probably the chapter images

20:46

group 43 - 47 (edited)

sure it's not pleasent to edit and sure our tools might not be good enough to edit it but I'm pretty sure every layer is needed to achieve the effect

mhh

20:46

then it would be a different bug

then i don't understand what u mean xd

but it works with an old client heinrich?

20:47

with ogl3?

#56 also has huge clipping values

i think they dont mean anything

or no

ok the debugger say

20:55

its crashing somewhere else xd

i'll just commit the fix with the font manager soon xd

anyone else getting startup crashes under windows sometimes?

22:20

@heinrich5991 u maybe?

I'm not using windows

mh

22:21

i even get crashes with the official release sometimes

that might be part of the problem – few of the devs use windows

rip

22:23

how can u code without vs ;~;

vs is a nice editor, but it doesn't run on linux

22:26

nowadays I use vim

u defs have 2 lifes

22:26

with vim xD

22:26

you need 2 lifes xD

22:27

it crashes at mem_alloc

sounds like memory corruption

and somehow destroys the pointer of the first memory header

22:28

yeah, but if valgrind doesnt report it under linux, that makes it strange

22:28

since vs and mingw both crashing sometimes

have you tried it in valgrind?

no but deen said nothing suspecious

ah

22:30

good

actually i got that crash since 10.x anywhere around that

yea, sounds like buffer overflow or so

but now its the first time it happened in debug mode

or use-after-free

yes

22:30

but at startup already xD

22:31

well gonna see if i find anything

22:31

i just don't trust SDL

22:31

its buggy shit

[Teeworlds] DDNet — JustDeepFly Top1 — 6:23.18

23:11

nemo: 2:16 – look at what crazy shit ppl map

a freeze jump?

23:13

+ the hook?

no, move right after falling through freeze

thats freeze jump

and move right after jumping through the freeze again

23:14

I would've though that freezejump included jump?

ah

23:14

u mean the thing after freezejump?

and before it

yea

23:14

not that special tho

as said in #general – I've never seen it before

ryozuki

the deepfly technique is harder than that small tricks

23:15

imo

what other maps use it

freeze jump is very common

23:18

the other thing, u usually do it for fun

i mean the glitch through the 1 tile freeze
